Precautions for Laser Diode Emission Check
When checking the emission of the laser diode during adjustments, never view directly downwards as this may lead to
blindness.
Precautions for Using Optical Pick-up (KMS-280A)
As the laser diode inside the optical pick-up damages by static
electricity easily, solder the laser tap of the Optical pick-up
flexible board when handling. Also take the necessary measures
to prevent damages by static electricity. Handle the Optical pickup flexible board with care as it breaks easily.
This MiniDisc player is classified as a CLASS 1 LASER
product.
The CLASS 1 LASER
PRODUCT label is located on
the bottom exterior.
IN NO EVENT SHALL SELLER BE

INCIDENTAL OR CONSEQUENTIAL
DAMAGES OF ANY NATURE, OR
LOSSES OR EXPENSES RESULTING
FROM ANY DEFECTIVE PRODUCT
OR THE USE OF ANY PRODUCT.

CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.
Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270°C
during repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering
or unsoldering.
Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be
damaged by heat.

SERVICING NOTE
1) When repairing this device with the power on, if you remove
the main board or open the upper panel assy, this device stops
working.
In this case, you can work without the device stopping by
fastening the hook of the OPEN1 switch (S801) with tape.

MAIN board
2) This set is designed to perform automatic adjustment for each
adjustment and write its value to EEPROM. Therefore, when
EEPROM (IC803) has been replaced in service, be sure to perform automatic adjustment and write resultant values to the new
EEPROM.
Refer to page 12 for details.

SELF-DIAGNOSTIC
2-1. GENERAL
This set uses the self-diagnostic system in which if an error occurs
in playback/recording mode, the error is detected by the model
control and power control blocks of the microprocessor and information on the cause is stored as history in EEPROM.
By viewing this history in test mode, it helps you to analyze a fault
and determine its location.
2-2. TEST MODE SETTING
There are two different methods to set the test mode:
1 Short BP801 (TEST) on the main board with a solder bridge
(connect pin @§ of IC801 to the ground). Then, turn on the
power.

while it being depressed.
2-4. RELEASING THE TEST MODE
For test mode set with the method 1:
Turn off the power and open the solder bridge on BP801 on the
main board.
For test mode set with the method 2:
Turn off the power.
2-5. SELF-DIAGNOSTIC MODE
1. Go into the test mode.
2. With the unit LCD indicators all flashing, press DISPLAY key
to go into the self-diagnostic mode.
2 In the normal mode, use the keys on the unit to perform the
following operations:
Press and hold down ( and press the keys below in this turn:

*1) Total recording time
Total recording time is recorded in minutes as an index for load to
the OP. It is recorded in hexadecimal format and up to 65,535 min.
(about 886 discs of 74-minute disc) can be counted. It returns to
“0000h” when recorder goes beyond this limit.
Example :REC 000A n Approx. 10 min.
REC 00A0 n Approx. 160 min.
REC 0A00 n Approx. 2,560 min.

2-6. CLEARING THE ERROR INDICATION CODE
AND TO TAL RECORDING TIME
After repair, reset the error indication code.
Reset the total recording time when you have replaced the OP.
1. Go into the self-diagnostic mode. (See page 5.)
2. To reset the error indication code, slide REC c key when
the code is displayed.
(All data including 1st, N , N-1 and N-2 are reset.)
3. T o reset the total recording time, slide REC c key when the

TEST MODE
4-1. GENERAL
This set provides the Overall adjustment mode (Assy mode) that
allows CD and MO disk to be automatically adjusted when in the
test mode. In this Assy mode, the system discriminates between
CD and MO disk and then automatically perform adjustments for
them in sequence. If a fault is found, the system displays its location. Also, the Serv o mode allows each indi vidual adjustment to be
automatically adjusted.
